When my grandfather passed away, he was creamated. In the memorial service we held for him, my younger cousin sighted him in the back of the room. It was odd for us to hear him talking about it.
My grandfather was in the airforce many years ago. After the service my cousin asked his mom, "didnt you see grandpa in the back of the room? You couldnt miss him mom. He was back there talking to the other men, but his uniform was different." :o This was almost impossible for him to know b/c there arent any pictures of my grandfather in his uniform. My cousin was 9 (i think) at the time of the service. I believed he saw him, as most of the family did. We all believe in spirits, ghosts, enitity's etc......
